hi all! I have a problem, all shaders that use a samplerCube map look totally black, I don´t know if it is a problem of my opengl version (2.1.2), my drivers, the compiler (NVIDIA 1.2 Cg compiler) or what…

Your cubemap texture has to be bound to the GL_TEXTURE_CUBE_MAP_EXT binding point when draw command is executed. So, in general case, you should bind it every time you draw something using it. Alternatively, you can include this binding into the display list you use for drawing.

minor: AFAIK, you don’t need to bind it each time before a side is filled with data.
